Pushbuttons on the Selection Screen
Drucktasten auf DynprosTo create a pushbutton on the selection screen, you use:
SELECTION SCREEN PUSHBUTTON [/]<pos(len)> <push>
USER-COMMAND <ucom> [MODIF ID <key>].
The [/]<pos(len)> parameters and the MODIF IF addition have the same function as for the formatting options for
underlines and comments.<push> determines the pushbutton text. For <push>, you can specify a
text symbol or a field name with a maximum length of eight characters. This character field must not be declared with the DATA statement, but is generated automatically with length <len>. The field must be filled before the selection screen is called.For <ucom>, you must specify a code of up to four characters. When the user clicks the pushbutton on the selection screen, <ucom> is entered in the UCOMM of the SSCRFIELDS
interface work area. You must use the TABLES statement to declare the SSCRFIELDS structure. The contents of the SSCRFIELDS-UCOMM field can be processed during the AT SELECTION-SCREEN event.REPORT DEMO.

BUT1 = 'Button 1'.
BUT3 = 'Button 3'.
CALL SELECTION-SCREEN 500 STARTING AT 10 10.
CASE FLAG.
WHEN '1'.
WRITE / 'Button 1 was clicked'.
WHEN '2'.

This example defines four pushbuttons on a selection screen that is displayed as a dialog box. The selection screen is defined in a statement chain for keyword SELECTION-SCREEN.
If the text symbols TEXT-020 and TEXT-040 are defined as 'Button 2' and 'Button 4', the four pushbuttons appear as follows on the selection screen displayed as a dialog box.
CLI1, CLI2, CLI3 and CLI4 are used for <ucom>. When the user clicks one of the pushbuttons, the AT SELECTION-SCREEN event is triggered, and the FLAG field is set. The FLAG field can be further processed during subsequent program flow after the user has chosen Execute.
